just got these and i skate very often indoors i love them but was a bit dissapointed when i realized that what looked like the real back spin remix wheels (the reason i picked this package)they were actually the back spin remix LITE which are plastic insted of metal :( which im sure helps with added weight since you already have a heavy skate but so far they have proven themselves only time wil tell tho-- my last set of skates lasted 8 months i am really hoping for years with theese.
